  Several preferred embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings.

  1 to 3 show a molded window panel assembly 10 having a window panel portion 12 with a peripheral edge 14 and a peripheral edge 16. For example, as shown in FIG. 1a, the window panel unit 12 has a large number of through holes 12a for a hinge, a movement adjusting device, and a latch mechanism for mounting the molded window panel assembly on a tailgate of a passenger car. The peripheral edge support portion 18 is molded on the peripheral edge portion 14. Of course, if necessary, the peripheral edge supporting portion 18 may extend substantially along the entire peripheral edge portion 14 of the window panel portion 12. The peripheral support 18 comprises at least one internal through hole, in this example two internal through holes 20, which from the introduction position indicated at 22 for supplying power and / or fluid, It extends along the peripheral edge 14 to a distribution position indicated by 24. The illustrated cover plate 24a is for covering the distribution position after deployment.

  In this example, the molded window panel assembly 10 has a second introduction position indicated at 26. This may be desirable to deliver one or more of power or fluid to the delivery location 24. Of course, if necessary, two or more distribution positions 24 may be provided. A power window wiper unit is provided at the distribution position, while another power or fluid consuming device, such as a brake light, is provided at the second distribution position. As can be seen, the molded window panel assembly 10 is a rear window of a vehicle, such as a sports utility vehicle as shown in FIG. 1a, but other embodiments include, for example, only a residential or commercial building window. Rather, mention may be made of window panel assemblies for other applications such as all-terrain vehicles, motorcycles and ships as indicated by 10b, 10c and 10d in FIGS. 1b, 1c and 1d, respectively. In addition, the window panel section is formed from a laminate of glass, plastic and other materials, especially from polymeric materials other than glass, such as those known under the trade names LEXAN (TM) and PLEXIGLASS (TM) it can.

  Referring to FIG. 2, it can be seen that the internal through hole 20 accommodates at least one power cable 28 and that the power cable substantially occupies the internal through hole 20. However, the power cable 28 does not have to fill the entire inner through hole 20, but may simply be loosely accommodated. Alternatively, the power cable may essentially form a through hole. In this case, the tube will be provided by the outer sheath 28a of the power cable 28. In FIG. 3, the power cable 28 is provided with a shared connector plug 28b for connection with a window wiper unit (not shown).

  Referring to FIG. 2, the molded window panel assembly 10 includes a preform member having an intermediate support portion 30, that is, a tube portion 32 including the internal through hole 20. Referring to the embodiment shown in FIG. 5, the intermediate support 30 comprises a groove section 34 having a pair of spaced flanges 36 extending from the body 38. As can be seen from FIG. 2, the spaced-apart flange 36 engages with both surfaces of the window panel portion 12, but if necessary, an intermediate support portion 30 having another shape can be adopted. 1 to 3, the main body portion 38 includes the internal through hole 20, but this through hole may be formed adjacent to the main body portion 38 if desired.

  Referring to FIG. 1, the adhesive layer 40 is disposed on the main body 38 between the spaced flanges 36, and the main body 38 and the peripheral end 16 are joined by the adhesive layer 40. . The adhesive layer 40 may be made of a material known under the trade name MYLAR, or of other materials that can withstand the temperatures that are exposed during the plastic molding process. If desired, this adhesive layer can be provided on both spaced flanges 36 and / or on the inner surface 38a of the body 38. The adhesive layer 40 may be provided continuously or at regular intervals or irregular intervals. Alternatively, the intermediate support portion 30 may be formed so that when the intermediate support portion 30 is assembled to the window panel portion 12, a fairly close frictional fitting state is obtained.

  In one variation as shown in FIG. 4, the body portion 38 has an inner surface 38a, which is spaced from the peripheral end portion 16 to form an internal cavity 42 to include an internal through hole. . Thus, the power cable can be placed in the internal air gap 42, in the internal through hole, or both, as required.

  Referring to FIGS. 6 and 8, the tube 32 can accommodate one or more power cables 28, as shown in FIG. 6, or one or more, as shown in FIG. 8, if desired. It can be integrally formed with the intermediate support 30 to accommodate the power cable 28 and / or one or more fluid pipes 46.

  The molded window panel assembly 10 can be manufactured in a variety of ways, for example, by an injection molding (or also known as encapsulation) technique as shown in FIG. In some embodiments, the intermediate support 30 can be molded in place with the two power cables 28 in advance. An adhesive layer 40 is provided on the inner surface 38 a of the main body portion 38, and the main body portion 38 is attached to the peripheral edge portion 14 of the window panel portion 12.

  After placing the intermediate support in place, the window panel 12 is placed in a mold with its forming cavity 52 positioned adjacent to the peripheral edge 14 (the two engagement dies being indicated at 50). .

  With the window panel portion and tube portion in place, the flowable material has sufficient conditions to form a peripheral support portion at least in a portion of the peripheral portion and to embed at least one tube portion. And supplied to the forming gap. After a suitable curing time, the window panel assembly 10 can be withdrawn from the molding cavity 52.

  If desired, a structure can be used to protect the power cable 28 and seal the mold in the area of the delivery location 24 during the molding process. For example, as shown in FIG. 10, the preform block 54 can be sized to fit the dimensions of the delivery location 24 and can be provided with an internal cavity 54a for receiving the power cable 28 therein. In this particular embodiment, the molding gap 52 is enlarged at 52a to accommodate the preform block 54. Alternatively, the preform block 54 may have a shape that closely fits the molding gap 52, and in this case, it is not necessary to enlarge the molding gap 52.

  Although the window panel assembly 10 uses an intermediate support, it will be appreciated that other approaches can be utilized to place the tube in place within the molding cavity. By way of example, the tube can be secured directly to the peripheral edge 16 of the window using, for example, an adhesive or adhesive material, a clip or other fastener.

  Although the present invention has been described with respect to what are presently considered to be the preferred embodiments, the invention is not limited thereto. On the contrary, the invention is intended to cover various modifications and equivalent arrangements encompassed within the spirit and scope of the appended claims. The claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements and functions.

  Thus, the window panel assembly 10 provides a peripheral support formed in the window panel, and the window panel assembly 10 is conveniently located in a power cable or fluid hose, radio or other communication antenna or such internal hole. One or more through holes are provided therein for other possible vehicle or other accessories and / or reinforcement cables, such as reinforcement members such as glass fibers or steel fibers.
